During my Cisco Academy days I bought the Cisco 806 Broadband Router - a fixed-configuration dual Ethernet platform.
I turned the unit off for the summer semester and when it was turned back on - it no longer worked. The TX/RX lights on both the Internet and LAN sides are steady-on.
I sent the unit to Cisco, in return I got a refurbished unit - 3 times I did this - 3 times I got a new serial-number box with the same problem. I contacted the TAC about this, and they deny ever having heard of this issue before. I can't be the ONLY person to have that happen - and with new refab boxes from Cisco too.
In order to get the box to run correctly, I usually opened the top and took out the RAM while the power was ON, then tunred off the power, reset the memory, and then turned it back on. Then it worked, if not I would repeat until it worked - about 2-3 times did the trick.
So, I sent unit 2 back to Cisco, and 2 weeks later I have unit 3 - another refab unit.
Same thing, only this time, I can't get it to work at all.
It appears to be happening when the IOS tries to load - decompressing the image I guess is where the error occurs.
It has the correct IOS in the correct location. Memory is OK, hardware is OK.
I can't get to the console at all - so I used the output I had from the last time it did stop working with at least rmon access.
Does anyone know how to fix this box? Ever heard of this before?
Can you send me the error message with which the router stops booting?. With that error message, I can trace out the root cause of the problem.
Looking at ur problem,. I need to get clarified regarding the following aspects;
1.Did u check the power source received?.I mean from the main.is that normal?
2.Which ethernet device u r conecting to 806 router, a hub or a switch or a modem?.Ensure that they are working properly.
Follow these guidelines while connecting the devices to the router:
1.Connect the color-coded cables supplied by Cisco Systems to the color-coded ports on the back panel.
2.If you must supply your own cable, see Appendix A of the below mentioned url for cabling specifications. If this appendix does not provide specifications for a particular cable, we strongly recommend ordering the cable from Cisco Systems.
This is the url that explains about hardware installation of 806 router.
Follow these guidelines when connecting devices to your router:
